Re: Universal Compute Unit (UcU)

This is probably a useful unit, but it should be some form of "balanced" composite, like the old IBM "a mip. a meg, a gig", meaning 1 MIP of CPU, 1 MB of memory and 1 GB of disk. I suspect this is what you were thinking of...

If it were just a CPU unit, I could easily have a 10 UcU system which gave me half the performance of a 5 UcU system because the first one was low on I/O bandwidth and the second wasn't.

It doesn't have to be a perfect balance: estimating quanta based on TPC benchmarks works surprisingly well, even though everyone games the benchmarks. Perhaps because they all game the benchmarks.
